To elucidate the manifestations of ocular injuries in the colored corn starch dust explosion at a Taiwan water park.
This is a retrospective, non-comparative, consecutive-interventional case series. Fifty explosion-injury patients on 27 June 2015 treated at Chang-Gung Memorial Hospital, Linkou, were included. Thorough ophthalmic examinations were based on emergent triage and consecutive ophthalmological consultations. Multiple ocular and systemic parameters were assessed.
Of the 100 eyes in the 50 cases reviewed, 22 cases were male and 28 cases were female. The mean age was 22.08 ± 4.64 years, and the mean burn total body surface area (TBSA) of patients was 45.92 ± 20.30%. Of the 50 patients, 20 had Grade 1 ocular burns, and the others were without ocular involvement. Two of the 20 cases that presented Grade 1 ocular burns died within 1 month due to other systemic complications. The most common ocular manifestations among those with ocular injuries included periocular swelling (75%), followed by conjunctival chemosis (65%), conjunctival hyperemia (50%), singed eyelashes (20%), cornea epithelial defects (10%), and punctate keratopathy (5%). It is worth mentioning that one patient developed herpes simplex keratitis due to stress 3 weeks after being burned. Half of the 50 patients had facial burns. Specifically, the patients with a greater TBSA presented more significant ocular-burn manifestations than those patients with lower TBSA.
Prompt ophthalmologic consultations are particularly necessary for mass burn-casualty patients with facial burns, inhalation injuries, and greater TBSA. The inspection and control of all ignition sources and the manipulation of dust with low concentrations and in an open space are crucial factors to prevent future dust explosions.
阐明台湾某水上乐园彩色玉米淀粉粉尘爆炸所致眼外伤的表现。
这是一项回顾性、非对照、连续干预的病例系列研究。纳入2015年6月27日在林口长庚纪念医院接受治疗的50例爆炸伤患者。基于紧急分诊和连续眼科会诊进行全面的眼科检查。评估了多项眼部和全身参数。
在回顾的50例病例的100只眼中，男性22例，女性28例。平均年龄为22.08±4.64岁，患者的平均烧伤总面积（TBSA）为45.92±20.30%。50例患者中，20例有1级眼烧伤，其他患者无眼部受累。20例有1级眼烧伤的患者中有2例因其他全身并发症在1个月内死亡。眼外伤患者中最常见的眼部表现包括眼周肿胀（75%），其次是结膜水肿（65%）、结膜充血（50%）、睫毛烧焦（20%）、角膜上皮缺损（10%）和点状角膜病变（5%）。值得一提的是，1例患者在烧伤后3周因应激发生单纯疱疹性角膜炎。50例患者中有一半面部烧伤。具体而言，烧伤总面积较大的患者比烧伤总面积较小的患者眼部烧伤表现更明显。
对于有面部烧伤、吸入性损伤和较大烧伤总面积的大批烧伤患者，及时进行眼科会诊尤为必要。检查和控制所有火源以及在开放空间中对低浓度粉尘进行处理是预防未来粉尘爆炸的关键因素。
